2 Features

Texas Instruments MSP430AFE253 with 2kB Flash and 512 bytes of RAM, plus 24-bit A/D

8MHz Ceramic Resonator

8-position 100-mil pitch screw terminal block for 3 differential analog inputs, V
ref
and ground

8-position 100-mil pitch male pin header for easy access to 6 GPIO pins, power and ground

Mini USB connector supplies 5V power and access to virtual com port for serial

On-board USB-to-serial converter IC for easy serial port communication and 3.3V supply

1 pushbutton for hardware reset of the MSP430 MCU

2 pushbuttons for user input

Texas Instruments’ Spy-Bi-Wire debug interface via 4-pin 100-mil pitch male pin header

Blue LED for application-defined visual feedback

RX and TX LED’s for visual feedback of USB-to-serial converter communication activity

1x3 x 100-mil pitch male pin header for external 3.3V power input and ground

2 removable jumpers for isolating the RX/TX lines from the USB-to-serial converter IC

USB-to-serial converter can be completely removed from the circuit via 3 removable jumpers;
one for UART RX, one for UART TX and one for the 3.3V supply. Allows verification of ultra-low
power consumption features of your application on the MSP430. Alternatively, provides easy
connection of other TTL UART hardware, such as GPS, Bluetooth modules, etc.
